Abstract

PURPOSE:To provide an insulating material with a low heat resistance, that is, with a use of the resin made capable, by making a construction of the insulating film applied after a process of annealing. CONSTITUTION:After a work of cutting, punching, etc. processed for a steel plate 1, with an insulating film not applied to its surfaces, a process of annealing is operated at an optimum temperature for magnetic characteristic, and after a process of annealing, a resin insulating layer 2 is constructed at a suitable temperature (below 300 deg.C).
